SIG Sauer P365 Upgrades

The SIG Sauer® P365 – introduced in 2018 – earned industry awards right from the start. At the time, sub-compact pistols rarely had a capacity of more than seven rounds. The P365 with a flush-fit magazine held 10 rounds and came with an extended magazine holding 12+1 rounds of 9mm.

The pistol was an outright game-changer from the start.

Grayguns supports the P365 platform with performance components for the P365 family of handguns, including the P365XL, P365X, P365 X-Macro, P365 FUSE and P365 AXG Legion. (All current models.)

Our lineup features straight and hybrid triggers, laser-sculpted grip modules, magazine releases and more.

All Grayguns trigger component upgrades are designed to maintain the manufacturer's safety values.

This page includes more than 30 SIG P365 products.
